Arctic Cooling has
provided Marns CDA with its patented Arctic Cooling Pro2LTC fan. This
fan is slightly different then your standard 80mm case fan. The first
thing I noticed is that the depth of this fan is considerably wider then
most other cooling fans I've seen. Most 80mm case fans are around 25mm
and the Pro2L TC is 34.5mm. I am not sure if
this detail will
increase the products performance, but it will be observed during the review. The main feature that Artic Cooling
is trying to sell is
its temperature control system to reduce sound levels in your case. We will
find out later if the product stands up to this claim. Another difference I
noticed from this product is the light placements. There are 4 LED's
placed inside the frame itself. This aspect is hard to describe, so please take a
look at the following pictures further into the review, for better details.

This is a case fan, so installation is pretty basic. AC uses the 3 pin
motherboard connector for power and RPM controls so if you do not have a 3
pin available, you will need to purchase a converter for your standard 4
pin 12v Molex. All in all, the install is standard. Nothing new, just
mount the fan on the case using the 4 screws provided and plug the 3 pin
connector into your mother board.

Appearance

The overall appearance is
not too bright nor too soft. There is just enough lighting accent to be noticed.

I am impressed with the pre-sleeved wiring. This
factor is a big plus, even if it's
white, it's still less you need to pay for
and time saved.

Performance

The graph above
provided by Arctic Cooling shows how the temp controls in the fan are supposed
to run at lower temperatures. The lower RPM's the fan runs is to maximize
sound reduction whenever possible.

After I ran some basic tests using a few heat
points, it was pretty much my conclusion that the RPM compared to
temperature are the same as the graph provided. So rather then show
these results twice we will just refer to AC's image above.

In reference to the sound, we placed this fan in a case
and turned off all of the other fans and there was no sound noted, other then
the PSU fan. Even with the case open the sound was so slight in
comparison that I was dumbfounded.

Quality

The thickness and quality of this mold
fan is far superior to
your stock case fan. The plastic is rigid so be careful if you don't use
the standard hardware. The after market ultra coarse thread you get at Home
Depot tend to be a bit rough on the plastics.

You must remember though this is a fan its not a $30 heat sink
or a $200 video card. The most important thing is that it performs to
specification, and that it pushes air. Then worry about style. The Pro2L
TC fan has
both.

Another interesting note is that
Arctic Cooling went through the trouble to patent this design, meaning generally
they did something special that no one else has done. This is most likely
being the temp control combined with the light placement and technology
involved with this fan. Now I don't know the exact reasons for the
patent or what feature was so special, but I agree this is a unique fan.

Pros

The
price is right. The quality you get with this fan is a great buy.

The
temperature control works awesome.

Sound
of this fan is considerably lower then many of its competitors.

Quality
is more then satisfactory.

Cons

It can only hook up to a 3
pin without converter and they do not provide the 4 pin converter.Note: I don't think this fan was
intended to not have RPM control though and this you would lose with the
4 pin connection.

Conclusion

If your looking for a nice fan that will auto-adjust
to your case temp, you found it. This quality fan does exactly what they
promise and for a very reasonable price. The only draw back is the
single connector type, but that is by design so I am not sure if this is
a flaw.
This is a very nice, cost effective fan. I recommend this for anyone
looking for a quiet, well made product for cooling a case. We award Arctic
Cooling the Marns CDA "Blue Ribbon Seal of Approval" for a
high quality all around fan.
